How to pack the data from laptop to computer?

Hi, as I see in the title, I wonder because I do not want to load my whole steam spile again

Because I have pretty slow internet

Can draw a LAN cable between them, use a USB stick or an external hard drive.

I would take the time-consuming path and re-download everything. Have already made negative experiences that Steam does not recognize the folder and still runterläd everything new

Thank you but I have to try it because it takes forever a gigabite duration with me sometimes 1 hour or 2 hours
